Variable within liquid if statement when calling shopify settings

Question

I thought this would be simple to solve but I am trying to put a variable within a liquid statement.

I have my variable {{ loop_index }} and I want it to be within this statement :

{% if settings.dropdown-[loop_index]-select  %}

I tried putting [...] round it but that didn't work. Basically it should say settings.dropdown-1-select, settings.dropdown-2-select.

What am I doing wrong?

Answer 1

Create a string containing the variable name, then use the square bracket notation to access the setting with that name. For example:

{% capture var %}dropdown-{{ loop_index }}-select{% endcapture %}
{% if settings[var] %}
